PRODUCT INFORMATION
Introduction
The Cooper Power Systems VARAdvisor Capacitor Bank
Neutral Monitor (CBNM) is cable-mounted and provides
feedback as to which capacitor banks may be offline due
to a fuse operation. The VARAdvisor CBNM consists of an
integral clamp-on sensing unit with a patented clamping
mechanism that allows one unit to be used on cable
sizes from 0.25” to 2.0”. The utility can set threshold limits
on neutral current that will alert them of a potential fuse
operation thereby reducing the need for physical bank
inspections. Default values from the factory set the current
threshold at 30 A and the reset threshold at 2 A. When
2 A or less is sampled, the device will automatically reset.
The VARAdvisor CBNM is weatherproof, submersible, and
meets or exceeds IEEE Std 495™-2007 standard.

INSTALLATION PROCEDURES
Overhead Capacitor Banks
1. Arm the VARAdvisor CBNM clamping mechanism
by carefully grasping both clamping arms, pulling
them apart until the trigger mechanism drops in
place. Stops have been built into the clamping arms
such that they can only be opened to the point where
the trigger will latch (See Figure 2).
2. For applications where the cable diameter is
less than 1”, leave the clamp pads attached to
the clamp arms. On installations where the cable
diameter exceeds 1”, remove the pads that are
attached to each clamping arm. Removing the pads
will allow the clamping mechanism to properly attach
to larger diameter cables (See Figure 3).
3. Apply a thin layer of silicon lubricant to the inside
of the closed core current transformer (CT).
4. Attach the VARAdvisor CBNM to a shotgun (clamp)
stick using the pulling eye.
5. Push the VARAdvisor CBNM onto the combined
capacitor bank neutral conductor. Ensure that the
CT is around the conductor and good contact is made
between the ends of the CT. The triggering mechanism
will release the clamping arms from the latched position
to securely attach the device to the cable.
Removing the VARAdvisor Sensor
1. Insert the hook end from the shotgun stick into the
pulling eye of the VARAdvisor CBNM and lock the
shotgun stick tight against the device body.
2. Pull straight back on the hotstick making sure that
the center of the cable is centered on the parting
line of the current transformer. This will assist the CT
in opening, allowing the cable to exit.
3. If clamp pads must be used with the VARAdvisor
CBNM upon reinstallation, ensure that the pads are
properly attached to the clamp arms.
Figure 3.
Remove clamp pads attached to each clamping arm
on a mechanism where cable diameter exceeds one
(1) inch.
SETUP PROCEDURE
Initial Setup
1. Once the device is properly installed, use the S.T.A.R.
Manual Reset Tool (SMRT) to activate the Reed Switch
(See Figure 4). A stamped “R” on the outside of the
sensor housing indicates the location of the Reed
Switch. Press the Reset Tool firmly to the “R” and the
LED blink sequence will begin to indicate the switch
has been successfully activated (see Table 1).
2. If the Normal Calibrated Sequence is displayed, the
sensor is ready for installation. For other blink sequences,
see Table 1 for explanation and recommended
actions.

VARAdvisor Capacitor Bank Neutral Monitor (CBNM) Commissioning and Installation Instructions
Operating Description
The VARAdvisor sensor takes a current sample every
hour. Every 14 days, the device will send out the daily
minimum and maximum current samples taken.
If a sample exceeds a user-defined and configurable
value (default = 30 Amps), the unit will send out a
notification packet via wireless communications. The
utility will be notified of an imbalance current that has
exceeded threshold no more than an hour after it appears.
The device will then revert back to the default reporting
frequency (14 days). To allow automatic reset of this
status a reset threshold will be used.
If at any time a sampled value is equal or less than the
reset threshold, the device will clear (zero) the over-current
status, power up the radio and report a data values
message. A new two week interval is initiated at this time
and collection of data begins again. An initial default value
of 2 A is recommended for the reset threshold.
Configurable Parameters
The VARAdvisor CBNM provides the general GridAdvisor
product configurability. In addition, it allows certain
VARAdvisor CBNM parameters to be configured as
detailed below. (Note: The Cooper Power Systems
Software Integration team will have to configure the
devices for the utility. In the future, this functionality will be
added to the Yukon GridServer software.)
History Report Period
The history report period for the device defines the
frequency, or number of days between, history reports.
The default report frequency is set at the maximum period
of 14 days. The configurability range is limited in firmware
to 1 – 14 days. It should be noted that increase frequency
will affect battery life.
Configuration Report Period
The configuration report period defines the frequency, or
number of history reports between, configuration reports.
The default configuration report period is set to 6 (~3
months). The configurability range is 0 (never/disabled) to
256 (almost never).
Over-current Trigger Threshold
The over-current threshold parameter defines the value
of current for which the device will enter an over-current
state. The configurability range is limited in firmware to
a maximum of 90 A (determined by the device’s ADC
saturation point of ~100 A) down to 6 A above the reset
threshold (hysteresis delta).
If the host attempts to reconfigure reset and over-current
thresholds to values too close to each other, the firmware
will adjust the configured values so that the minimum
hysteresis delta is maintained.
Reset Threshold
The reset threshold defines the value of current for
which the device will reset its over-current state. The
configurability range is limited in firmware to a minimum
of 0 A up to 6 A below the over-current threshold (thus
maximum would be 84 A if over-current threshold was
maxed at 90 A).
Reed Switch Testing/Activation
During installation, the operator can identify the
onboard configuration is valid and that the device and
communication path are functional through the use of the
Reed Switch. The Reed Switch is activated by swiping
the ink-stamped ‘R’ on the side of the housing with a
Manual Reset Tool (SMRT).

SAFETY
FOR LIFE
Table 1 describes the LED sequences for the different
device states. The LED blink sequence for history
reporting is only enabled if triggered by the Reed Switch.
(See Figure 4.) Upon detection of a Reed Switch trigger,
the device will slow blink the LED 3 times and then
initiate a current read. Current readings may take up to
15 seconds to complete, during which time the LED will
be OFF. The device will then initiate a new LED blink
sequence, power the radio and make a data report. Any
data collected in the previous two week interval will also
be transmitted at this time (Note: The LED will continue
to blink until communication has been completed and
the radio is powered down). The type of LED blink will
indicate whether the device is calibrated, and if it is in
over-current state. Any over-current flags will be cleared
at the start of the Reed Switch toggle and be reset based
upon the new current reading. A new two week interval
will begin following this operation.
